Application filed June 15,

My present invention has reference to building structures andparticularly to structures of brick and concrete, and my object is toembed at determined spaced intervals in the building construction metalplates which have means at the ends thereof for tying the same together,the said plates being formed with and provided at determined spacedintervals with casings for a molding block so that the said block hasits outer edge CID arranged flush with the inner wall surface andwhereby molding boards, studs or other plankings may be nailed to theblock to materially assist in the molding of the concrete wall, as wellas to provide a means for securing studs or battens to the inner face ofthe wall so that laths or the like may be secured to such battens.

A further object is the provision of a device for this purpose in whichthe casing of the improvement has a top that is yieldable so that thewooden block may be readily inserted in the casing and held therein byclips, the lower wall at the outer edge of the casing being formed witha bendable portion designed to afford a downwardly extending apron tocontact with the inner face of the wall and thereby insure the properposition of the plate which carries the casing in the wall structure.

To the attainment of the foregoing and other objects which will presentthemselves the improvement also resides in certain other novel featuresof construction, combination and operative association of parts, onesatisfactory embodiment of which is disclosed by the accompanyingdrawing.

In the drawing:

O Figure 1 is a horizontal sectional view through a wall structureprovided with the improvement.

Figure 2 is an inner face view thereof.

Figure 3 is a perspective view of the improvement.

Figure 4 is an enlarged sectional view approximately on the line 4 4 ofFigure 1.

Figure 5 is a plan view of the blank from which the casing is struck.

As disclosed by the drawing the improvement contemplates the employmentof any 193i. serial No. 544,635.

desired number of metal plates 1. Each plate, at one of its ends, isformedv with an 'aperture 2, and at its other end with anupstandlng-stud 3. The studs of the respective plates are designed to bereceived in the apertures of the cooperating plates and whereby theplates will be sustained in parallelism and in interlocking engagement.

The plates are of desired lengths and each of the plates, atpredetermined and equidistantly spaced intervals has'secured thereon thebase 4 of a metal casing. The upper wall of each of the casings isextended at a downward angle from the rear wall 5, so that there is asubstantially wedge-shaped pocket provided between the upper yand lowerwalls. The rear walls of the casings are indicated for distinction bythe numeral 5 andfare arranged in a line with the inner edges of theplates l and the upper walls of the said casings are indicated by thenumeral 6. The lower wall 4 is extended a suitable distance beyond theouter wall 6 and the said lower wal-l and its said extended portionadjacent to its edges is slitted to form outer bendable clips 7 and acentral bendable plate in the nature of an apron 8. A wedge-shapedwooden block 9 is arranged in the casing, and thereafter the clips 7 arebent upwardly against the outer reduced face of the block 9 and over thetop 6 of the casing. The central portion 8 of the bottom wall 4 of thecasing is bent downwardly so that the same will be arranged flush withthe inner face of the wall 10.

The casing construction permits of the ready insertion of the woodenblock thereon, the said block being clamped in the casing by thebendable clips 7 and the apron contacting with the outer face of thewall limits the inward movement of the casing in such wall andconsequently holds the plates 1 in proper longitudinal alinement. Theouter reduced edge of the block is exposed so that molding boards orplanking may be tacked f thereto when the improvement is employed in theconstruction of concrete walls, and likewise when such molding boardsare removed studs or battings may be nailed to the blocks. It is, ofcourse, to be understood that the casings and the respeetive series ofplates l are arranged directly above each other throughout the length ofthe wall. The substantially wedge-shaped body of the casing having itswidened end received in the wall structure prevents the accidentalremoval of the said casing when the same is embedded in either aconcrete or a brick Wall. Nails may be readily driven into various partsof the exposed edge of the wedge block 9 and Withdrawn therefrom in aneasy and eX- peditious manner. Should the driving of the nails into theblock cause the splitting of the said block, this will only tend toforce the top and bottom of the casing away from each other and to bunchthe split block in the casing.

Having described the invention, I claim:

A plug for either a concrete or brick wall comprising a casing to beembedded in the wall, said casing being constructed from a single sheetof metal to afford a bottom, an inner end wall extending at a rightangle from the bottom and a top which is of a less length than thebottom and which is arranged at a downward angle with respect to thebottom, a wed e-shaped block designed to be received in t e casing,bendable clips integrally formed on the corners of the bottom designedto be bent over the top and to hold the top a ainst the wedge block andfor sustaining t e wedge block in the casing and said casing having itsbottom, between the clips, formed with a depending apron to Contact withthe outer face of the Wall to hold the plug in proper position in thewall structure.

In testimony whereof I afiiX my Signature.

JAMES MGLAUGHLIN.
